My Water Service - What do I need to know?

Frequently Asked Questions About Water Service

As a home or property owner, what should I know about my water service?

Home and property owners are responsible for maintaining and repairing their water service from the City water main in the street to the building, including all internal plumbing.

Should I install a water softener in my home?

South St. Paul water has a hardness of approximately 18 grains (307 ppm), which is considered relatively high. A privately owned water softener or softening service may help reduce scale buildup and improve water quality.

What is causing low water pressure in my home?

Low water pressure is often due to a malfunctioning water softener. To verify, check the pressure at an unsoftened tap (e.g., an outdoor faucet). If the pressure is normal there, the softener may need servicing. Average system pressure in South St. Paul is 65 psi.

What should I do if I suspect a leak outside?

Contact South St. Paul Public Works at 651-554-3225 (M–F, 7:00 a.m.–3:30 p.m.). After hours, weekends, or holidays, call 911. Staff will inspect the leak and determine if it’s the homeowner’s service line or the City’s water main. If the leak is on the homeowner’s side, a licensed contractor must make the repairs. If it’s the City’s main, repairs will be made at no cost to the owner.

What if I have a leak inside my home?

First, try to isolate the leak by shutting off the valve near the appliance or the main valve near the water meter. If you cannot shut off the water, contact Public Works at 651-554-3225 (M–F, 7:00 a.m.–3:30 p.m.). For emergencies outside business hours, call 911 to have the water shut off at the exterior valve box.

Why is there sand in my water?

Sand-like particles are usually caused by a malfunctioning water softener. These particles may collect in faucet screens, appliance filters, or toilet tanks. Refer to your softener's manual or maintenance provider for assistance.

Where should my sump pump drain hose discharge?

Sump pump discharge hoses must drain to the outside of the home. They are not allowed to discharge into the sanitary sewer system, including laundry tubs or floor drains.

What are some preventative steps I can take?

• Operate valves annually to ensure they work properly (contact a plumber first if the valves are old or have never been used).
• Inspect all valves and the water meter for leaks.
• Check kitchen, bath, utility room appliances, and plumbing lines for leaks.
• Listen for running water in toilet tanks. Use food coloring in the tank (not the bowl) to test for hidden leaks.
• Clean faucet aerators regularly.
• Inspect sprinkler systems for leaks—look for soft ground, standing water, or unusually green patches of grass.
• Check outside hose spigots and hoses for leaks or to confirm they are shut off.

These preventative actions can help reduce costly repairs and conserve water, lowering your utility bill.
